Series Connection of Coupled Inductors: Let there be two inductors connected in series, with self inductances L1 and L2 and mutual inductance of M. Two kinds of Series Connection of Coupled Inductors are possible; series…

Inductively Coupled Circuits: Inductively coupled multi-mesh circuits can be analysed using Kirchhoff s laws and by loop current methods. Consider Fig. 10.17, where three coils are inductively coupled. For such a system of inductors we…

Ideal Transformer on Load: Transfer of energy from one circuit to another circuit through mutual induction is widely utilized in power systems. This purpose is served by Ideal Transformer on Load. Most often they transform…

Coefficient of Coupling: The amount of coupling between the inductively coupled coils is expressed in terms of the coefficient of coupling, which is defined as where M = mutual inductance between the coils L1 =…

Dot Convention in Coupled Circuits: Dot Convention in Coupled Circuits is used to establish the choice of correct sign for the mutually induced voltages in coupled circuits. Circular dot marks and/or special symbols are placed…

Mutual Inductance of Coupled Circuits: Mutual Inductance of Coupled Circuits - A voltage is induced in a coil when there is a time rate of change of current through it. The inductance parameter L, is…

Coupled Circuits Definition: Two circuits are said to be 'coupled' when energy transfer takes place from one circuit to the other when one of the circuits is energized. There are many types of Coupled Circuits…
